IMPROVEMENT IN W|NDOW'SASHES.

Specification forming part of Letters Patent No.13,032, dated June 12, 1855.

To all whom it may concern:

Be it known that I, W. S. FORD, of the city county, and State of New York, have invented a new and useful Improvement in Hinged or Folding Sashes, commonly termedefLFrench Windows 5 and I do hereby declare that the following is a` full, clear, and exact description of thesame, reference being had tothe annexed drawings, making a part of this specification, in whiehf Figure l is a front view of my improvement. Fig. 2 is ar'vertical transverse section ot' the same, ao x, Fig. l, showing the plane ot' section. Fig. 3 is a horizontal section ot' the saine.

Similar letters of reference indicate corresponding parts in the several figures.

The nature of myinvention consists in placing the sashes within the casing or fra-me so thatsaid sashes may be raised or lowered like the ordiuarywindows, and also be opened and closedmlike/thd'French windows, by swinging' on hin/ges, asiwill'be presently shown and described, whereby/'inthe bottom stop-bead may be used and' the windows rendered weathertight, and also secured withoutthe fastenings now required for French windows.

A represents the casing or frame ofthe window, which is constructed in the manner precisely similar'to those made for the ordinary sliding sashes. Within the upper part ot' the casing there is placed a small sash, B, which is fitted between' the outer ledges or beads, c, of the casing'or'frame and the parting-heads b. This sash B has cords c and -weights d attached to it, the cords working over pulleys c in the sides of the casing or frame, and slides in the casing or frame, the same as the upper sash of ordinary window s.

C C are two sashes, which occupy thegreater portion ofthe casing or fra me A, and are about of the same proportion as the French windows. The sashes O are attached by hinges j' to strips y g, which work between the stopbeads h and the parting-bead b. The inner sides of the strips g gare beveled, and also the inner sides ofthe parting-beads b and the stopbeads h, and the strips g g are thereby secured Y between the parting-beads and stop-beads in dovetail form, as shown clearly in Fig. 8. The strips g are allowed to slide up and down between the parting-beads b and the stop-beads 7L, and have cords t and weights j attached to them, the cords working over pulleys 7c in the sides of the casing or frame. (See Fig. 3 and dotted lines in Fig. 1.) It will be seen4 that as the sashes C are attached to the strips g g by hinges both the strips and sashes may be raised and lowered, like the ordinary sliding windows. The back stiles of the sashes C are providedvwith lips l, which, when the sashes are closed, fit in recesses m in the back sidesA of the strips g and form a Weather-proofjoint. (See Fig. 3.) The stop-bead h extends all around the inner edge of the casing or frame A, as usual, as shown in Fig. l, and consequently when the sashes C C are' closed and shoved down the lower edges of the sashes C will be on the outer side ofthe bottom or lower stop-bead, and as the sashes open or swing inward it will be seen that the bottom stop-bead serves as a fastening. In order, therefore, to open the sashes C, they are first shoved upward within the casing or frame till their lower edges are above the bottom stop-bead, h, as 'shown in red, Fig. l. The sashes C may then be swung inward.

The above improvement obviates the great objection to French windows-the dit'ticulty of making them weather-proof. The storm will beat underneath the lower edges of the sashes and the sill of the casing or frame. Numerous devicesI have been invented to prevent thiselastic weather-strips, Ste.; but they are liable to get out of order, and are not effectual, and,

besides, add to the expense of construction.

With the ordinary French windows French fastenings are also required, which are expensive, and the better kinds nearly as complicated. as a bank lock.

In my improvement no fastening is required to keep the sashes G closed, for the bottomY stop-bead, h, effects this, and also renders the sashes at their lower ends perfectly weather- Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

Constructing folding hinged or French windows as herein shown, or in an equivalent way, so that thel hinged sashes C C may be raised and lowered, the same as`the ordinary sliding sashes, and also be allowed to swing as French sashes, whereby said sashes are kent closed without the application of any special fastening, and also rendered perfectly weatherproof, as herein described. 1
